Find the diameter of circle using pythagoras
d = √(Δx² + Δy²)
d = √((7-1)² + (-6-2)²)
d = √(6² + (-8)²)
d = √100
d = 10
The diameter is 10
Find the circumference
c = π × d
c = 3.14 × 10
c = 31.4
A trapezoid has 4 sides. You have everything you need, just add them together. The perimeter of this trapezoid is 40.3 inches or 3.358 feet.
Hello!
Your answer should be 26.85.
We can use the formula of pi d or 2 pi r for the circumference.
You would get 5 pi.
But since its not a full circle you would divide it in half and get 2.5 pi.
2.5 pi is equal to 7.85.
Now we can use the equation 7.85 + 7 + 7 + 5
That would equal our answer... 26.85!
Hope this helps!
Height x base is the formula for parallelogram
5.25 x 12 = 63
